摘要：本文测定了在２０～１００℃温度范围内，四个不同聚合度的聚二甲基硅氧烷的热压力系数和密度。建立了一个能够计算各种聚合度的ＰＤＭＳ热压力系数的公式，并据此得到了它们的恒温压缩系数、内压等重要物理性质。ＰＤＭＳ的这些性质对聚合度都不太敏感。
Thermal pressure coefficients and densities for four poly-dimethyl-siloxanes which have different degree of polymerization were measured over the range ot temperature from 20 to 100℃.A relation between the viscosity,density and thermal pressure coefficient for PDMS was established and some improtant physical properties, such as compressibility and internal pressure etc.were calculated. It was found that these properties of PDMS are not susceptible to the degree of polymerization.
